United
Devices.
I'm not going into any copyrights mumbo-jumbo here, but noone forces you to use the images supplied with the addon.
You can make your own, if you prefer.
Also, as the subteam idea isn't copyrighted as LK pointed out, I don't see any obstacle in the way for one to create his own subteam for some other UD team.
Conclusion: You can use this addon without getting sued.
LK: This mod does actually add the person's UD rank to his profile, and is displayed in topics, below their user status.
